Clean Line Resource Conservation
This project at an aircraft engine case over-haul facility involved the replacement of tanks in an existing cleaning line with a new more efficient system in terms of energy, water and chemical use.
The original clean line tanks consisted of a number of open un-insulated, 6000 litre tanks, containing chemical cleaning agents and rinse water.
The two new replacement machines reuse water in a closed loop, minimising water, energy and chemical consumption.
The contents of the old tanks had to be disposed of periodically as hazardous waste. This new line results in a reduction of such hazardous waste.
Achievements include:
• Reduced water consumption
• Reduced natural gas usage
• Reduced chemical usage
• Reduced hazardous waste
• Increased production speed
• Reduced emissions to atmosphere
• Improved air quality within the building
• Reduced chemical handling risks
• Reduced manual handling risks
• Reduced air extraction rates
Hazardous waste generation has reduced by 40% or approximately 18,000 litres per annum since the new system became operational in the first quarter of 2005.
